BlackBuck 8M - 8A Buck Laser LED Constant Current Driver
BlackBuck 8M - 8 Amps compact driver for portable and engraving devices.
The high-performance, compact buck LED/laser diode driver with thermal protection (external NTC sensor) . Can be controlled/modulated by an external sources like DAC, PWM or analog modulated signal. It has 5V reference voltage output for connecting an external potentiometer as a modulation source. High-quality onboard multi-turn trimmer helps to the fine-tuning of the output current. The driver can operate with the current up to 3A without an external heat sink, but it requires a heat sink for currents above 3A. It works fine with 2 or 3 cells Li-Ion or Li-Po batteries or 7-12V DC PSU.

- The item comes with NTC sensor
- Avoid short circuit and reverse polarity connection, it will damage the driver!
- The contact pads on the PCB are very small, if you do not have enough skills in soldering, I highly recommend not to buy this driver.
